Innovations Introduction to Copper Mining amp; Extraction

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

Nonferrous extractive metallurgy

In general, prehistoric extraction of metals, particularly copper, involved two fundamental stages first, the smelting of copper ore at temperatures exceeding 700 176;C is needed to separate the gangue from the copper; second, melting the copper, which requires temperatures exceeding its melting point of
